To the users of Photoshop software to explain the detailed analysis of the eight salvage waste pieces of useful skills experience.
Share eight pieces of simple techniques to repair scrap, respectively, two compositions, direct fill, confusion color temperature, black-and-white contrast, histogram, reject meat, excessive sharpening, local sharpening.
Every time after taking photos on the computer to check, found that many photos have problems, such as poor composition, under exposure or exposure, blurred picture and so on. Delete these photos and feel pity, but there is no time for fine adjustment, how to do? The old wolf to introduce a few simple rough methods, in response to a large number of photos, very useful.
Secondary composition, cut out good photos
Many people take pictures and press the shutter speed faster than the brain thinks. Many photos do not notice the composition of the problem. Fortunately, the digital camera now has a large pixel, we can easily cut to the second composition. Using the clipping tool in Photoshop, the cropped box is a nine-Sudoku, which is just as a reference for our tailoring. Nine Sudoku Composition form: The screen to "well" is divided into nine of the same shape, cut will express the theme of the theme scenery or characters placed in the intersection of nine equal parts, the sky and the ground preferably in the upper and lower 1/3 position.
With the Crop tool, there are 8 control points around the clipping box, and using it, we can widen, increase, shrink, and enlarge the box. If you put the mouse near the corner of the cropping box, you can see that the mouse will turn into a double-headed arrow with a corner, at which point we can rotate the cropping box to an angle. According to the principle of the composition of the three-point method, after cutting the area, double click the mouse in the middle of the cropping box to make the second composition cut.
Two, gray sky blue, direct fill color
Sometimes, the weather is very good, but it is not enough blue, in the strong sunlight film The sky is a pale. If you want to use Lightroom or camera raw to say how to tune, but also long speech. As a rough way, directly fill color, although the drug is very fierce, but the effect is to control their own. Open the picture you want to adjust, and add a new layer to the layers panel. Then use the Line Selection tool box to select the part of the sky, fill in blue, and then set the layer mode to "multiply" in the layers panel, based on the principle of "multiply": when any color overlaps with black, it produces black, and the color remains unchanged when any color and white overlap. If you fill the sky with the ground part of the light, fill with a blue to white gradient fill.
If you feel the color of the sky is too deep, you can use the opacity setting in the layers panel, reduce the transparency of 50% or less, and finally use the "Hue/Saturation" (menu: Image → adjust → hue/saturation), do the overall color adjustment, changed the sky, if there is water in the picture, also pay attention to the color of the water to unify.
Third, the chaos of color temperature, a recruit fresh
Even if the current high-end SLR, in the complex light environment will also be misjudged, usually we encounter the most on the shooting night, a variety of different light color temperature mixed, the color will be very serious.
Left: Indoor red and yellow light staggered, red light dominate, photo overall red? Right: Use the automatic color effect in Photoshop
Methods: Using Photoshop "image → adjust → automatic color" can be easily changed, this function will be based on the screen in the relationship between black and white to change the screen white balance, correct accuracy of up to 80%. The rest of the curve adjustment tool to adjust, such as changing the contrast and the light and shade relationship can be. This method of adjustment is useful in most cases. But there is a light source can kill all digital cameras, almost powerless to save, that is the yellow light source.
In the yellow light source, the digital camera basically loses the white balance correction function, moreover this kind of light source, later also did not save. So try to stay away from this light when taking photos.
Provides a very useful photo filter in Photoshop, menu: "image → adjust → photo filter". In the color selection of the filter, we can choose the yellow opposite cool colors, or use the opposite filter to try. Although can not completely correct the white balance of the screen effect, but the glare of the yellow to be very good control.
Four, black and white contrast, easy to change HDR
In the light contrast intense environment, the photograph picture intensity and shade form the intense contrast. For the sake of conservatism, smart photographers usually light the lights, the middle color, the dark part, each one, and then synthesize a perfect HDR photo. When too much trouble, then how to solve the later?
In the context of light and shade contrast, the choice of neutral hue measurement is the balance.
In menu: "image → adjust → shadow/highlight". According to the change of the picture, adjust the shadow and the slider on the high light at the same time, observe the change of the picture until satisfied. Is it feeling a little HDR photo now?
V. Exposure error, histogram to emergency
In the shooting, we have a number of reasons for the shooting screen error, the photograph is not too bright, too dark, is too gray. For this kind of photos, all use curve adjustment tool, suggest to use Photoshop CS3.0 above version, adjust window has histogram display. About the histogram of understanding and understanding please consult the relevant information, it is necessary to study hard.
Histogram overflow to the left, too dark, the lower left corner of the adjustment point upward shift, the adjustment point is also upward adjustment to observe the color changes in the screen, until satisfied.
Histogram overflow right, too bright, overexposed. The adjustment point in the upper right corner is shifted downward, and the adjustment points are adjusted downward to observe the color change of the picture until satisfied.
There is a section on both sides of the histogram without pixel display, the dark and bright parts are not deficient, the adjustment points on both sides to move. The adjustment points in the middle are adjusted according to the color change of the screen until satisfied.
Six, reject the meat, clear point again clear point
The photo is not clear enough, in addition to our shooting technology, but also with the camera we use, lenses have a lot of relationship, such as the dog's head shots are "meat" (the picture is soft, not sharp enough to say). There is also no attention to using the imaging best aperture (F5.6~F13). For those "meat" we still make it sharper and look more comfortable.
The left side of the original film seems very clear, but magnified to 100% a look, it is uncomfortable, the screen is too soft, this is the obvious meat, feeling soft. Use Photoshop's Sharpening filter: "Filter →USM sharpening." For sharpening the "quantity", "radius" and other values to be based on the size of the photos and the actual requirements of the set, can not mechanically use the fixed parameters. Such sharpening can be an "immediate" change for those with slight blurring and for lens reasons.
Seven, sharpen, do not use addictive
When sharpening, the photos need to be handled carefully, sharpened, and the photos are prioritized to look very comfortable. After sharpening, the picture will be distorted, giving people a dry feel, look uncomfortable. So like sharpening can, but do not addictive.
Let's take a look at several sharpening tools in Photoshop. Open a photo in Photoshop, then click the menu: "filter → sharpen", we can see about 5 kinds of sharpening tools, below the old wolf choose 4 of them to speak about their characteristics.
USM Sharpening: This is the old Wolf favorite Sharpening tool, from the previous use of Photoshop 6.0, has been this function, the main advantage is easy to control, sharpening effect of nature. When used, do not drag the sharpening quantity of the slider excessively, the excessive will appear a certain halo effect. Further sharpening: This is a lazy person's operating mode, it is easy to appear sharp excessive agitation, old wolf General not, unless it is to do some production, need strong contrast effect, such as outdoor posters. Edge Sharpening: This is also a more useful sharpening tool, it is mainly to improve the edge of contrast, you can make the contours of the picture clearer, the old wolf general use it to sharpen some of the contour of the photos. But sometimes the phenomenon of sharpening excessive, use to be careful to use. Smart sharpening: This is another lethal weapon that started appearing in Photoshop CS2, it also contains a "Gaussian mold", "lens blur", "dynamic mode" three kinds of sharpening way, the old wolf compared to sleep in which the "lens blur" the best sharpening effect, the other two easily distorted, And USM sharpening a ratio.
Eight, sharpen, distinguish between primary and secondary
Photo in sharpening, the best way is to sharpen the focus of the photos, such as the following macro works, in the sharpening, we are only insects and stamens made local sharpening, so that the main object clearer.
The local sharpening method is very simple, you can first copy the original photos in the layers of the layer board, then click the Mask setting in the Layers panel, then set the foreground color in the tool panel to black, use the brush tool, set a larger-than-fit pen effect, and then smear the place where you don't need sharpening. has been applied to the place to retain the original effect, no smear is the place to sharpen the effect.
Well, the above information is small compiled for you photoshop This software users brought to the detailed eight salvage pieces of useful skills to share the full content of the experience, you see the users here are very clear now, and hope to bring useful help to everyone.
